In this paper we analyse the complexity of boolean functions takes value 0 on a sufficiently small number of points. For many functions this leads to the analysis of a single function attains 0 only on unsigned representation of numbers from 1 to d for various d. Here we obtain a tight bounds on the DNF complexity of complete functions in terms of the number of literals and conjunctions. The me...

As a sequel to comparison between reports by parents, we compared behavioral/emotional problems of 6-11-yr-old Thai and American children reported by teachers. These revealed higher ratings for Thai than for American children on nearly all problems showing significant cross-national differences. Thai children were rated higher on both overcontrolled and undercontrolled behavior and had more ove...

Two case examples of school shootings in Finland illustrate the interplay between the distal, international influence of the Columbine shooting and the more immediate impact of local peer interactions involving both peer bullying at school and peer encouragement of violence through the Internet.
